Abstract
We present statistical evaluations of wideband spatial

dual-polarized radio channel measurements. Some 80 different street-level transmitter positions in downtown

Helsinki, Finland, were measured. We chose three different

receiver array sites below, at, and above the roofop level of the surrounding urban environment. A super-resolution algorithm allows the determination of the directions of arrival of incident radio waves at a 16x62 elements base station antenna array. The main conclusion of our investigations is that the incident waves tend to cluster in azimuth, elevation and/or delay, which we justify by detailed statistical evaluations.

Clustering is mainly dejined by the surroundings

Clustering is mainly dejined by the surroundings

of the base station. The cumulative distribution jimction of the powers of these clusters shows that in 90% of all cases, 75% of the total received power is concentrated in the two strongest clusters. Street guided propagation dominates at all three receiver sites, even if the base station is above the roofop level. (Less)
